siding-at Vienna., Empire of Austria, have clear, and exact description of the invention,

such asx'will enable othersskilled'in the art to Whi'ch it appertains to make and use the same. 1 'M'y invention relates touaiming devices which may also be used as vvautomatic electric lfiring devices for guns and being more particularly designed for guns on board ship. In'v my improved device` tivo points are brought to coincidence or, into contact with each other at themoment when, owing. tothe training of the gun and tli'e ship s motions the plane ofthe, trajectory of the projectile goes v exactlv through the targeta-nd the inclination o the gun to the horizontal 'plane by the i elevating gear and the motion of the ship corfresponds exactly to the distance of the gun from the target (the range).and to the vposition of the target relatively to the horizon.

[lin arnrffis secured to the sighting device 2." Fcrfcilitating the explanation of my inventionit is assumed fora moment thatthe point 4'at"thef.free end of this arm 3 is exing devi'y e a's-isindicatcd in dotted lines in rected-- upon the target the point 4 is exactly in the vertical plane passing through the targetand ythe p tical axis of the sighting device. jectory of theprojectile to be iii-cd 'lrom'the projectile mayhit the target, the horizontal distance between. the optical axis of the.

gun, as well as any lateral deviation of the irojectile resulting from any cause whatever, being neglected. The sighting device is moreover so held that the said vertical plane passes through the point 1, called hereinafter the main pivot point.

6 is a. frame free to turn around the geeinetrical axis. of the said bar or shaft 5 passA ilg through the min pivotpoint and'perinanentlyv parallel to the axis ol the bore of the gun, This frame is provided wit-h an arm 7 and is permanently held in a vertii. al plane by weights o1. otherwise so that the point 8 at the free end of the arm 7 ispermanently held in thc vertical plane passing through. the axis 5. This plane is again neglecting the horizontal distance between the axis 5 and the axis ol' the hereof the gun and any lateral deviation of the projectile, the plane of the trajectory of the projectile' to be tired from the gun and its line of intersection with the vertical plane passing' through thi` sighting line, that to say the optical axis oi the sighting 4device directed upon the target is the vertical line through the main pivot point l. lf now the point #i enters the latter vertical plane theplane ofY the tri'ijectory of the projectile coincides exactly withtlzis vertical plaine and the grin is correctly trained horizontally.

.The arm 7 is adjustable in the frame 6 along an are ol a circle' having` the main pivot point 1 for its center according to the distancebetween *be vtarget and the gun the Fig. I so that when the sighting devicev is di- 6o ac tly inline 1with the optical axis of the sight- With t is planethe plane of thojtragun must exactly coincide in order thatf-ihe' sighting device andthe axis of the bore ofthe saine as the usuai orecch or rear sight o." guns.

The. distance lbetween its4 point 8 and the main pivot 1 isthe same-as that between the latter and the point 4 of the arm A3,'and the shape and-,size of the. ami 7 areso chosen that' when its point 8 entersthe vertical lane passing throu h the sighting line and wllien it is properly a justed in accordance with the distance between target and gun and when the angle between the sighting line and the axis (whichis the same as the angle between the sighting line' and the axis of the comes into contact or coincides with the" tE oixiit 4.. At this moment aswill be seen om. the above explanation theI plane of the i trajectory of the projectilet'o he fired from the ngun coincides with 'the gle between, e sighting line and the axis of the bore of the gun (or the axis 5) corre.- spoiids exactly to the range, so that when the gun is fired at this nioinent the projectileis :sure to hit the target irrespective of the position ci the target relative to the horizon and irrespective o any oscillations of the ship and the gun. The firing of the gun in this moment may be effected either on command or aiitomaticall by means of an electric circuit closed by t e two points 4 and 8 making contact with each other as is indicated in Fi Y. 1. @he condition that the vertical plane through the sighting line shall pass through the main pivot point 1, may be fulfilled by inalging the sighting device'capable of turning round a spindle 9 the axis of which passes through the main ivot point 1, such spindle 9 boing capable oil) turning round the axis 5 and another axis 10 at right angles to both axes 5 and 9 and by arrangements for permanently holding the same vertically by moans of weights or by hand or otherwise; a convenient means for holding vertically the axis 9 consists in attaching tothe axis 5 an elastic saddle 37 similar to a bicycle saddle on wliic i the gun pointer is seated who by um in taining his equilibrium notwithstanding an): oscillatory motion of theship, such as rolling, will hold vertically the axis 9 .and also the iranicfsecured to the axis 5.

lt is not iiecessnryithat the point 4ishall be exactly 11i `liuc with the optical axisof the siglitiiigdevice that is to say .in lthe sighting lino, it may be placed out of this line prois'only necessary to vertical plane passing through the sighting line and the ari-.l 3'. t

ythis bloc assoc? vided that the point 8 of the arm 7 is shifted in the saine direction and to the saine extent horizontally and verticall Moreover it is thatythe said bar and the axis 9 are always heldin a vertical plane passing through the sighting line. In this case the points 4 and 8 must be the saine distance from the transverse axis 1U and the main` pivot point 1 will be the point of intersection of the axes 5 and 9. l

The arm 7 may be adjusted in accordance with ,the Y .range iii the following manner. This arni is carried by a bar 11 curved on the arc of a circle, the center of which is. the main .pivot point 1 or the transverse axis 10, the

ar 11 being guided in' curved frame 6. This (trian ular or quadrangular) in transverse Sectio and `is provided atv its ed fes with parts of ainale screw thread into w ich eiigages a nut 12 provided with a hand wheel 13 journaled in the frame 6 but prevented from moving longitudinally therein, such arrangement allowing of adjustment, but the bar 11 may be adjusted by any other suitable means. The corrections for any lateral deviation of the projectile as well as vfor the direction and speed of the onward movement of the target and the shiA carrying the gun are obtained as in the usua rear si hts bylaterally adjusting the arm 7. For t is'4 purpose the arm 7 is secured to a slide 14 (see also Figsi, 4F and 5) movable along a plate 1'5 fastened to the bai,`

the correspondingly bar` 11 is polygonal 11 such slide 14 being'operated b a stud v16 working in'a slot' in 'the slide as s iown more clearly in Fig. 4 and adjustable in accordance with the s eed of the target in a grooved blocklS, whic worm and worm wheel in accordance with the direction of the onward movement ofthe target until an arrow 17 fastened on thc stud 16 is parallel to suclr direction. The shaft of the worm wheel 19 is adjustable along a grooved block 20 so allowin for the strength of the wind and this bloci is adjusted by turning the same by means of a worm and worm wheel allowinir for the direction of thev The shaft oithe wheel 21 is adjust- .j

`required are imparted to the slide independently of one another sb allowing the arm 7 to be adjusted by'the entire amount of .This total correction when adj usted for a given position of the gun will be changed when the training of `the'gun is changed soas to remain accurate for all po- "sitions of the gun provided that the speed with each other while the gun is not accul rately trained and 1n case ot auto'l'tlc electric' firing the vpn would be fired, but the projectile woul( nnss the target, ln order to avoid thls the 'axis 1s extended downward beyond the main pivot point l. and to its lower end a casing 24 (see also Figs. 6, 7

and 8) is attached carrying a plate 25 upon which a ball 26 rests freely between four pendulums 27 suspended at the top ol'v the casing in. the corners of a square, at the lower ends ol` the pendulunis 27 and b elow the plate 2.)

contact piece28 are secured in such a ma nner that when the axis 9 1s exactly vertical in which case the plate 25 is exactly horizontal, each contact :piece 1s 1n contact with that diagonally pposite thereto. 'lhe contact piece oltwo pendulums at two adjacent corners ol the square are electrically connected with each other and the contact pieces of/the Apendulums atthe other corners ol the square one is connected with the point tand the other with Ithe point 8 a suitable source ol' electricityserving l`or\the purpose ol' tiring the gun being included in one ot these circuits. Now when the axis S) comes out ,oll the `vertical and consequently theplate 25 comes' outof the horizontal position at least one of the pendulums 27 willbe swung out which action will be assisted by tlu` ball 26 rolling on theplate while the pendulum diaglmally opposite to the irst named will be arrested bythe plate 25; therefore the contact between at least two contact pieces rv2% and consequently also the firing circuit will be brokelnwhereby the liring ol' thel gun is pre: vented when the axis .l is not exactly vcrtical even il` the points 4 and H arein crmtact' with'each other. I. I v

The axis l) is'normally vertical, the plate 25 horizontal and the contact pieces 28 are in contact with each other so that under normal 'conditions the gun can be fired electric.

ally only when the sighting device is directed upon a point ol the horizon, but if the target ias not in the horizon the axisl is no more exactly Vertical when the sighting device is di-I rected upon the target and consequently in By, these l means the casing 24'may be adjpsted in aelcordance with the range and the height of the target in such a manner that the plate 25 is 'exactly horizontal and the pendulums 27 arein contact position when the axis t) is in the vertical plane passing through the` line olA sight and the sightingdevice is directed exactly upon the target. A very fine adjustment of the casing 24' is not required;l'or instance a readjustnient of 'thiscasing is not necessary when with'one and the same target the range varies within rather wide limits.

AtV the lower. end of the barf 11 there is iattached a casing 31 (see also Figs-9, 10, I1) provided with a plate 32 and two )endul-ums 35, 35 andv which easing is adjuste in accord'- ance with the range andthe height of the target in such a manner thattheplate 32 is exactly horizontal and the penduhims 35, 35 hang exactly vertical touching lthis-plate, and contact pieces 36, 36 4at thelower end ot suchpendulums 'are in contact with. eachother, when .the axis 5 is in thel vertical plane passing through the line of sight andvis inclined to this line olt sight at an angle corresponding to therangeand the height of the target, Athat is to say at the correct elevation angle. The contact pieces are included =in the tiring circuit being in series with the contact pieces 28 and the points 4 and 8. When therefore the axis 5 is not in the properdirection oris thrown out of -this direction owing to a sudden movement of theship one ol' the pendulun'is 35 will be swung out where-` by the contact pieces 36, 36 will be separated. and thus the liring circuit broken. This action isv assisted by two balls 33, 34 freely resting on the plate 32 andv separated by a web in the easing 31., one or the other of these ballsvroll toward the outer edge of the plate and pushes outward the pendulum adjacent thereto whenever the plate 32 is not exactly horizontal." j

llt will be seen that the easing 31 has to -be adjusted to the desired elevation of range, and thegun can onlybe fired when it is at suchA elevation, and at no other time. When the range is changed, then, of course,' the casing 31 has to be re-adjusted to corre-A spond. This adjustment may be eieeted in `its pivot in the bar V11 rio any desired way, by'turning the easing on Fig. 12 shows a convenient form of firing device, which may be used in the apparatus, but is not of itself a 'part of thc invention. 'lhis tiring device comprises a primer 4() secured in and insulated from the metallic bottom of the cartridge slell 41 proyidedwith an inwardlyprojectin point 42. Opposite this point there is provided in the cartridge anot ier point-43 electrically connected to the cartridge shell. i

, 44 is a iiring pin mounted in and insulated from the breechblock 45. One terminal of a source of electricity is connected to the firing pin, and the other to the breech bloeit; the contacts 4, 8, 36, 36, 27, 27, and 28 are included in series in the electric circuit. When the firing pin 44 is in the firing position, as shown in Fig. 12, the spark will cross the gap between the points 42 and 43, vand the cartridge will be fired.
